Tree water uptake patterns across the globe

Plant water uptake from the soil is a crucial element of the global hydrological cycle and essential for vegetation drought resilience. Yet, knowledge of how the distribution of water uptake depth (WUD) varies across species, climates, and seasons is scarc ...

Tree diversity reduces variability in sapling survival under drought

Charlotte Grossiord, Jingjing Liang, Xiaojuan Liu

Enhancing tree diversity may be important to fostering resilience to drought-related climate extremes. So far, little attention has been given to whether tree diversity can increase the survival of trees and reduce its variability in young forest plantatio ...

From roots to canopy: Unraveling the influence of species diversity on tree water relations under warmer and drier climates

Eugénie Isabelle Mas

The worsening of drought events with rising air temperature alters tree water relations causing severe hydraulic impairments and widespread forest mortality. Mixing tree species with contrasting hydraulic traits could reduce forest vulnerability to extreme ...

Interactions between beech and oak seedlings can modify the effects of hotter droughts and the onset of hydraulic failure

Charlotte Grossiord, Eugénie Isabelle Mas, Hervé Cochard, Margaux Clara Lou Didion-Gency, Janisse Deluigi, Fernando Valladares

center dot Mixing species with contrasting resource use strategies could reduce forest vulnerability to extreme events. Yet, how species diversity affects seedling hydraulic responses to heat and drought, including mortality risk, is largely unknown. Using ...

Lignin, from biomass waste to sustainable materials for food packaging, antiviral coatings and agriculture

Alice Boarino

Our planet has been challenged for years by our reckless use of fossil fuels, which has led to the ongoing climate change and energy crisis. The transition to the use of renewable alternative sources has now became urgent and inevitable. The valorization o ...

Increasing temperature and vapor pressure deficit lead to hydraulic damages in the absence of soil drought

Pascal Turberg, Charlotte Grossiord, Eugénie Isabelle Mas, Laura Mekarni, Philipp Schuler, Leonie Corine Schönbeck

Temperature (T) and vapor pressure deficit (VPD) are important drivers of plant hydraulic conductivity, growth, mortality, and ecosystem productivity, independently of soil water availability. Our goal was to disentangle the effects of T and VPD on plant h ...

Phloem water isotopically different to xylem water: Potential causes and implications for ecohydrological tracing

Andrea Rinaldo, Paolo Benettin

The stable isotopes of hydrogen and oxygen in xylem water are often used to investigate tree water sources. But this traditional approach does not acknowledge the contribution of water stored in the phloem to transpiration and how this may affect xylem wat ...

Plant wax and carbon isotope response to heat and drought in the conifer Juniperus monosperma

Charlotte Grossiord

Plant waxes, including n-alkanes, are commonly used for a wide range of paleo-applications. Several common traits of n-alkanes that are used as paleo-proxies include chain length distribution and average chain length (ACL), as well as plant wax carbon and ...

On the use of leaf water to determine plant water source: A proof of concept

Paolo Benettin

Source water apportionment studies using the dual isotopes of oxygen and hydrogen have revolutionized our understanding of ecohydrology. But despite these developments-mostly over the past decade-many technical problems still exist in terms of linking xyle ...

Vegetation cover and plant-trait effects on outdoor thermal comfort in a tropical city

Gabriele Manoli, Paolo Burlando

An increase in urban vegetation is an often proposed mitigation strategy to reduce urban heat and improve outdoor thermal comfort (OTC). Vegetation can alter urban microclimate through changes in air temperature, mean radiant temperature, humidity, and win ...
